Defensive publication

ABSTRACT

A METHOD FOR PRODUCING AN IMPROVED SOLUBLE COFFEE PRODUCT WHICH COMPRISES SPLITTING THE EXTRACT DRAW OFF STREAM FROM A COFFEE PERCOLATION UNIT INTO TWO BATCHES, ONE BATCH CONTAINING HIGHER QUALITY AND HIGHER CONCENTRATION EXTRACT THAN THE SECOND BATCH CONTAINING LOWER QUALITY AND LOWER CONCENTRATION EXTRACT. THE SECOND BATCH IS EVAPORATIVELY CONCENTRATED WITHIN A CONTINUOUS EVAPORATOR WITH A UNIFORM RESIDENCE TIME OF LESS THAN ABOUT 30 SECONDS AND ADDED TO THE FIRST BATCH. THE COMBINED EXTRACTS ARE DRIED TO GIVE A SOLUBLE COFFEE PRODUCT WHICH DOES NOT PRODUCE SIGNIFICANT OFF-FLAVORS.
